Alright, let's solve this math problem step by step. First, we have the number 483. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 25. So, we're going to take the number 483 and add it to itself 25 times.
Step 1: 0 + 483 = 483
Step 2: 483 + 483 = 966
Step 3: 966 + 483 = 1449
Step 4: 1449 + 483 = 1932
Step 5: 1932 + 483 = 2415
Step 6: 2415 + 483 = 2898
Step 7: 2898 + 483 = 3381
Step 8: 3381 + 483 = 3864
Step 9: 3864 + 483 = 4347
Step 10: 4347 + 483 = 4830
Step 11: 4830 + 483 = 5313
Step 12: 5313 + 483 = 5796
Step 13: 5796 + 483 = 6279
Step 14: 6279 + 483 = 6762
Step 15: 6762 + 483 = 7245
Step 16: 7245 + 483 = 7728
Step 17: 7728 + 483 = 8211
Step 18: 8211 + 483 = 8694
Step 19: 8694 + 483 = 9177
Step 20: 9177 + 483 = 9660
Step 21: 9660 + 483 = 10143
Step 22: 10143 + 483 = 10626
Step 23: 10626 + 483 = 11109
Step 24: 11109 + 483 = 11592
Step 25: 11592 + 483 = 12075

So, 483*25 = 12075
